To all whom it may concern.-

Be it known that we, OHARLEs T. RoGERs and RAYMOND R. ROGERS, citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Vacuum Condensers, of which the following is a specification, reference being had therein to the accompanying drawings;

This invention relates to a vacuum condenser of the type wherein a definite quantity of material is treated and then removed and especially to means whereby the products of condensation are so trapped as not to return to the mass at the base of the condenser.

As herein shown, the invention relates especially to an apparatus for condensing milk, although obviously it is fitted for other purposes.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in central vertical section through the neck and exhaust portion of a'condenser which embodies features of the invention. Fig. 2 is a plan view of a condenser dome, partly broken away, and a distributing cone thereunder.

Referring to the drawings, 1 indicates the upper portion of the body of a cylindrical upright'condenser having a constricted vertical neck 2. The mouth of the neck is covered by a dome 3 of sheet metal or like suitable material which is supported at an interval above the neck by an annulus 4 likewise of sheet metal which is concentric 'With the neck, the inner wall of the annulus being separated from the neck by an interval or air space save at its upper margin 5 which is united to the edge of the neck to form a close-joint, the lower portion of the annulus being spaced and supported by a plurality of suitably designed brackets 6. An outlet or exhaust nipple 7 at the base of the annulus has pipe fittings 8 adapted for connection with any suitable exhaust pipe. A perforated ring 9 of greater internal diameter than the mouth of the neck is secured between meeting flanges 10 and 11 of the dome and the outer wall of the annulus by clamping bolts 12. This ring supports a distributing cone 13 in axial alinement with the condenser neck, its apex 14 being directly be neath a water inlet 15 fitted for proper supply pipe connections and is secured on top of the dome.

In operation the vapors or gases from the contents of the condenser strike the inner surface of the cone as they rise from the mouth of the condenser neck where they are condensed by contact with the water cooled surface and run down, dripping off the base of the cone outside of the condenser neck and trickling down the inner wall of the annulus.

The fine jets of water from the apertures of the ring likewise aid in trapping any gases or vapors which are not condensed by the cone and the water of condensation is readily drawn off through the outlet of the mouth of the annulus. At the same time, while thus thoroughly cooled, the vapors do not strike any cooling surface until clear of the mouth of the condenser as the wall of the neck is insulated from the water jacket or annulus supporting the dome by suflicient interval of air so that the contents of the condenser is substantially at its initial temperature until it is clear from the condenser neck. This entirely prevents condensation 0n the inner wall of the condenser itself so that liquid cannot return to the main mass of material being treated, thereby greatly increasing the efficiency of the condenser and lowering the cost of its operation.

The details of construction herein outlined are not'essential to the proper working of the device and many changes may be made therein without departing from the scope of the invention and we do not wish to limit ourselves to any particular form or arrange ment of parts.

Having thus fully described our invention what we claim is 1. A vacuum condenser having a body terminating in a vertical cylindrical neck, an annular water jacket for the neck connected at its upper end with the upper end of the neck and separated by an air space from the neck for the balance of its length, a perforated horizontal ring in the upper end of the jacket, an imperforate cone whose base rests on the inner margin of the ring, the inner diameter of the cone base being larger than the mouth of the neck, a dome over the ring and cone closing the upper end of the j aoket, a water inlet at the top of the dome discharging centrally over the cone, and an exhaust opening near the lower end of the water jacket.

2. A vacuum condenser having a body terininating in a vertical cylindrical neck, an annular water jacket forthe neck connected at its upper end with the upper'end of the neck, brackets at the lower end of the neck supporting the lower end of the acket with its inner wall in spaced concentric relation to the neck, a perforated horizontal ring in the upper end of the jacket, an imperforate cone whose base rests on the inner margin of the ring, the inner diameter of the cone base being larger than the mouth of the neck, a dome over the ring and cone closing the upper end of the jacket, a'water inlet at the top of the dome discharging centrally over the cone, and an exhaust opening near the lower end of the water jacket.

3. A vacuum condenser having a body with a contracted. upper portion, a vertical cylindrical neck secured thereon, a plurality of radial. brackets at the lower end of the neck, an annular water jacket whose interior diameter is greater than the outer diameter of the neck, supported on the brackets eoncentrically with the neck, the inner wall of' the jacket being inbent at its upper end and united to the upper edge of the neck, a perforated ring supported on the upper end of the outerwall of the jacket at an interval above the mouth of the neck, the internal diameter of the ring being larger than the outer diameter of the neck mouth, a condensing cone on the ring whose internal base diameter corresponds to the internal diameter of the ring, a cover seated on the ring over the cone, a water inlet in the cover discharging centrally into the cone and an exhaust outlet from the lower part of the water jacket.

In testimony whereof we affix our signa-
